Breast cancer is the most common type of cancer in women, both in the world and in the Republic of Croatia, and it was relevant to investigate the kind of view they have on their disease (breast cancer) through some psychosocial factors. The aim of the research was to examine the psychosocial factors of emotional adaptation in women with breast cancer, ie the degree of perception of the disease, the positive and the negative emotional experiences and the social support of the same. The research was conducted within the "All for Her" association on a sample of 102 participants. A four-part questionnaire was used for the assessment: general data, Disease Perception Questionnaire (Broadbent, Petrie, Main and Weinman, 2005), Positive and Negative Emotional Scale (Diener, Wirtz, Tov, Kim-Prieto, Choi, Oishi and BiswasDiener, 2010) and the Social Assistance Assessment Scheme (Abbey, Abramis and Caplan, 1985). The results showed that women suffering from breast cancer believe that treatment helps the disease and understand well their illness. They also show that there experience more positive emotional experiences than negative and have high social support. The results of linear regression analyis have been shown to be significant in predicting the criteria, ie observed predictor variables, social support, emotional and cognitive perception of the disease, explaining a total of 35% variance of positive emotional variables and 39% variance of negative emotional experiences. Correlation coefficients show that social support is associated with positive and negative emotional experiences and emotional perception of disease or more social support means less negative experiences, better emotional perception of illness and more positive experiences. The results obtained will be used to improve psychological assistance to affected women.
